day no. 16,797: kind, quality, and quantity

Matthew 7:17-20

Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles? Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit. A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. Wherefore by their fruits ye shall know them.

Trees are evaluated according to their kind, quality, and quantity. An apple tree brings forth apples and an orange tree brings forth oranges. A good apple tree brings forth good apples and a bad orange tree brings forth bad oranges. A productive apple tree brings forth many good apples and an unproductive orange tree brings forth few good oranges.

Matthew 13:8

But other fell into good ground, and brought forth fruit, some an hundredfold, some sixtyfold, some thirtyfold.

The best seeds and trees bring forth high quantities of high quality fruit in keeping with their kind. A good yield of good fruit is the goal. 

Matthew 21:19

And when he saw a fig tree in the way, he came to it, and found nothing thereon, but leaves only, and said unto it, Let no fruit grow on thee henceforward for ever. And presently the fig tree withered away.

The worst trees bring forth bad fruit or are barren altogether. They betray their kind by either begetting nothing of the sort or by wasting all their efforts trying to produce something that they can't.
